Black Spots Or Crusts In Cat’s Anus: Causes And What To Do


It can be concerning when you notice something unusual, like black spots or crusts around your cat’s anus. However, this occurrence isn’t always a cause for alarm. There are several reasons why this can happen, and many of them are quite harmless

The black spots or crusts around your cat’s anus could be something as simple as dry poop stuck in your cat’s fur or just your cat’s natural pigmentation, commonly seen in orange cats. Sometimes, what is seen is the normal openings of their anal sac ducts which can be spotted at the 4 o’clock and 8 o’clock positions or a dry anal gland discharge.

There are also other possibilities like fleas, scar tissue, or even medical conditions like anal sac disease or tumors. It’s a bit of a mixed bag when it comes to causes, and that’s why it’s important to get a clear picture of what’s happening.

No one knows your cat better than you do. You’re the one who notices when their appetite changes, when they’re not their usual playful self, or when they’re just not “right.” So when it comes to those black spots or crusts, you’re their first remedial step will be to take a closer look – are they grooming themselves excessively? Are they scooting across the floor? These signs might give you clues about the cause.

In the case of dry feces, a simple wipe with a damp cloth or a gentle trim of the fur around their bum can solve the issue. Flea infestation, anal gland diseases, tumors, or trauma will require medical intervention. You might also notice other related symptoms that would warrant a trip to the vet.

What Are The Black Spots On My Cats Anus?

1.Orange Cat Hyperpigmentation

Hyperpigmentation is a condition where certain areas of the skin become darker than the surrounding skin due to an excess of melanin, the pigment responsible for skin color. This condition is often harmless and can occur in any breed, but it’s particularly common in orange or ginger cats.

Orange or ginger cats are genetically predisposed to have more melanin in their skin, which may manifest as black spots around their anus and other parts of their bodies. These spots are simply a normal variation in skin color and typically do not cause any discomfort or health problems for the cat. However, any sudden changes in pigmentation or new spots should be checked by a veterinarian.

2. Openings Of The Anal Sac Ducts

The anal sac ducts are two small openings located on either side of a cat’s anus. These ducts are connected to the anal sacs, which are small, gland-filled pouches that produce a smelly fluid used for scent marking. In some cats, the openings of these ducts can appear as small black spots near the anus. This is a normal anatomical feature, and these spots do not generally cause any issues.

However, if you notice swelling, redness, or discharge around these openings, it could indicate a problem with the anal sacs, and you should consult your veterinarian.

3. Anal Sac Disease

Anal sac disease occurs when the anal sacs become inflamed, infected, or impacted. This can cause a range of symptoms, including pain, swelling, and redness around the anus, as well as scooting or excessive licking of the area. In some cases, the fluid inside the anal sacs may leak and dry around the anus, forming black spots or crusts. Anal sac disease can be caused by a variety of factors, including obesity, allergies, and frequent diarrhea.

If you suspect your cat has anal sac disease, it’s essential to consult your veterinarian for proper diagnosis and treatment, as untreated anal sac disease can lead to more severe complications, such as abscesses.

4. Dried Anal Gland Discharge

The anal glands, located within the anal sacs, produce a foul-smelling fluid that cats use for scent marking. When a cat defecates, this fluid is typically expelled along with the feces. However, sometimes the fluid can leak out of the anal sac ducts and dry around the anus, forming black spots or crusts. This dried discharge can be a normal occurrence, especially in older or overweight cats, but it can also be a sign of anal sac disease or other health problems.

Regularly checking your cat’s rear end for dried discharge, unusual odors, or other abnormalities can help you catch potential issues early. If you notice any signs of discomfort or changes in your cat’s behavior, it’s essential to consult your veterinarian for further evaluation.

5. Dry Poop Caught in Cat’s Fur

Some cats, particularly those with long or dense fur, may have feces trapped in the fur around their anus. Over time, this can dry and harden, forming black or brownish crusts commonly referred to as “dingleberries.” Dingleberries can be uncomfortable for your cat and may lead to skin irritation or infection if left unattended.

If you notice dingleberries on your cat, carefully trim the affected fur with scissors, ensuring not to nick the skin. Regularly grooming your cat and keeping the fur around the anus trimmed can help prevent the formation of dingleberries.

6. Fleas and Flea Dirt

Fleas are small, blood-sucking parasites that can infest your cat’s coat. Fleas leave behind droppings, known as “flea dirt,” which appear as small, dark specks that resemble black pepper or ground coffee. Flea dirt can accumulate in various areas of your cat’s body, including around the anus.

If you notice black spots or crusts on your cat’s anus, along with signs of itching, scratching, or skin irritation, it’s essential to check for fleas and flea dirt. If your cat has fleas, consult your veterinarian for appropriate flea treatment and preventive measures to protect your cat and home from further infestations.

7. Scar Tissue

If your cat has a history of injury, surgery, or skin infection around the anus, it may develop scar tissue in the affected area. Scar tissue is a normal part of the healing process but can appear as raised, thickened, or darkened skin, sometimes resembling black spots.

While scar tissue itself is not harmful, it can sometimes become itchy or uncomfortable for your cat. If you notice scar tissue around your cat’s anus, monitor the area for any signs of discomfort, redness, or swelling, and consult your veterinarian if you have any concerns.

8. Skin Tags

Skin tags are small, benign growths that can develop on your cat’s skin, including around the anus. They typically appear as fleshy, skin-colored, or darkened protrusions and can vary in size and shape. Skin tags are usually harmless and do not cause any discomfort or health problems for your cat.

But they can sometimes be confused with other skin conditions, such as warts or tumors. If you notice any new or unusual growths on your cat’s skin, it’s essential to have them examined by a veterinarian to rule out more serious conditions.

9. Blackheads

Blackheads, or comedones, are a form of feline acne that can appear as small, dark spots on a cat’s skin. While it’s true that feline acne is more commonly found on a cat’s chin, it can occasionally occur around the anus or other areas of the body. Blackheads result from clogged hair follicles, where the sebum (skin oil) and dead skin cells become trapped and oxidize, turning black.

In rare cases, these blackheads may appear around the cat’s anus, causing black spots. It’s essential to consult your veterinarian if you notice such spots, as they can help diagnose and treat the issue and rule out other potential causes of black spots in the area.

10. Apocrine Cysts

Apocrine cysts are benign cysts that can develop near a cat’s anus. These cysts are filled with a thick, oily fluid produced by the apocrine glands, which are located within the hair follicles. Apocrine cysts can appear as small, round, or oval lumps and may be mistaken for black spots if they are dark in color.

While apocrine cysts are usually harmless, they can sometimes become infected or rupture. If you notice any lumps or unusual growths on your cat’s skin, it’s essential to have them examined by a veterinarian to rule out more serious conditions.

11. Cancerous Cells

While less common, black spots on a cat’s anus can sometimes be a sign of skin cancer. Several types of skin cancer can affect cats, including melanoma, squamous cell carcinoma, and basal cell carcinoma. These cancers can appear as black or dark-colored spots, lumps, or ulcers on the skin. It’s important to note that not all black spots are cancerous, but any new or unusual growths on your cat’s skin should be examined by a veterinarian. Early detection and treatment are crucial for the best possible outcome.

12. Lentigo Simplex

Lentigo Simplex is a condition characterized by multiple black or dark brown spots appearing on the lips, gums, and eye margins. Only rarely, does it occur in the anus of cats. These spots are caused by an increase in the number of pigment-producing cells (melanocytes) in the skin. Lentigo is a benign condition and is not associated with any health problems.

What Are The Black Crusts Around My Cat’s Anus?

1. Dry Poop

Sometimes, small remnants of feces can get stuck around a cat’s anus. If not cleaned, these remnants can dry and harden, forming black crusts. This is especially common in long-haired cats, where fecal matter can become trapped in the fur. Regular grooming and cleaning of your cat’s rear end can help prevent this issue. It’s important to monitor your cat’s grooming habits and consult with a veterinarian if you notice recurring problems.

2. Dried Anal Gland Discharge

Cats have two small anal sacs that produce a smelly fluid, which is usually expelled during defecation. Occasionally, this fluid can leak onto the skin and fur around the anus, where it can dry and form black crusts. If the black crusts are accompanied by a strong odor, this may be the cause. Regular grooming and cleaning can help, but persistent issues with anal gland discharge should be addressed by a veterinarian.

3. Debris and Flea Dirt

Cats that spend time outdoors may come into contact with dirt, mud, and other debris that can accumulate around the anus and form black crusts as they dry. Additionally, cats infested with fleas may have flea dirt (feces of fleas) around their anus. Flea dirt appears as small, black specks and can sometimes be mistaken for regular dirt or debris. If your cat has flea dirt, it’s crucial to address the underlying flea infestation with appropriate treatments.

4. Scar Tissue

If your cat has had an injury, surgery, or skin infection around the anus, the healing process might lead to the formation of scar tissue. Scar tissue can sometimes appear darker than the surrounding skin, resembling black crusts. While scar tissue itself is not harmful, it’s important to monitor the area for any signs of discomfort, redness, or swelling. If you’re concerned about scar tissue around your cat’s anus or any associated symptoms, it’s essential to consult your veterinarian.

What To Do If Your Cat Has Black Spots Or Crusts In His Anus?

1. Inspect For Fleas & Ticks

The presence of fleas and ticks on your cat can lead to black spots or crusts around the anus. Flea feces, known as flea dirt, may appear as small black specks. Ticks can attach near the anus, causing irritation. Examine your cat’s fur and skin around the anus for these parasites. If you find fleas or ticks, consult your veterinarian for appropriate treatments and preventive measures to avoid future infestations.

2. Clean Bum With A Damp Cloth

Gently cleaning your cat’s anus with a damp cloth can help remove any fecal matter, dried anal gland discharge, debris, or other substances that may be contributing to the black spots or crusts. Use a soft, clean cloth or pet-specific wipe, being careful to avoid causing discomfort. Gently pat the area dry afterward to prevent moisture from lingering on the skin, which can cause irritation or infection.

3. Trim Your Cat Fur To Get Rid Of Dingleberries

Long-haired cats may accumulate fecal matter (dingleberries) in their fur around the anus. Carefully trim the fur in this area to prevent buildup and irritation. Use blunt-tipped scissors or pet grooming clippers and be cautious to avoid accidentally cutting the skin. If you’re unsure or uncomfortable doing this yourself, consider seeking assistance from a professional groomer or veterinarian.

4. Watch Out For Associated Symptoms

Monitor your cat for any additional signs of discomfort or health issues, such as excessive licking or scooting, redness, swelling, or unusual behaviors like hiding or changes in appetite. These symptoms may indicate underlying issues like anal sac disease, skin infections, or allergies. It’s important to address these associated symptoms promptly to prevent complications and ensure your cat’s well-being.

5. See Your Veterinarian If You Suspect Serious Medical Issues

If cleaning does get rid of the black spots or crusts around your cat’s anus, or if your cat exhibits symptoms of discomfort, it may indicate a serious medical condition such as anal sac disease, flea infestations, or trauma.

It’s crucial to consult your veterinarian for a proper diagnosis and treatment plan. Your vet can assess your cat, provide appropriate treatment, and recommend follow-up care or preventive measures. Early intervention is key to addressing any potential medical issues and ensuring your cat’s well-being.

What Do Worms Look Like On A Cat’s Anus?

Worms in cats may sometimes be visible around the anus. Tapeworms, for example, appear as small, rice-like segments that may be moving or dried up, while roundworms resemble spaghetti-like strands. If you notice any worms, it’s crucial to consult your veterinarian for a proper diagnosis and treatment plan, as different types of worms require specific medications.

What Are The Two Dots On A Cat’s Anus?

The two dots you might see on a cat’s anus are the openings of the anal sacs or anal glands. These sacs are located on either side of the anus at 4 o’clock and 8 o’clock positions and they produce a smelly fluid that is typically expelled during defecation. Sometimes, the sacs can become clogged, infected, or abscessed, leading to a condition known as anal sac disease. If you observe any unusual signs around your cat’s anus, such as swelling, discharge, or excessive licking, consult your veterinarian for an examination.

Something Sticking Out Of A Cat’s Bum

It is likely a rectal prolapse which occurs when a portion of the rectum protrudes from the anus. It may appear as a reddish, tubular mass sticking out from the anus. This condition can be caused by factors such as straining during defecation, constipation, diarrhea, or trauma.

Rectal prolapse is a medical emergency and requires immediate veterinary attention. Your vet may gently push the prolapsed tissue back into place, treat any underlying causes, or recommend surgery in severe cases. Do not attempt to correct a rectal prolapse yourself, as this can cause further damage.

Wrap Up

If you’re a cat owner, it’s natural to be concerned when you see black spots or crusts on your pet’s anus. Fortunately, understanding the possible reasons behind these occurrences can help put your mind at ease and guide you on how to address the issue.

The presence of black spots or crusts around a cat’s anus can be attributed to various causes, ranging from benign to more serious. Some possible explanations include dry feces, anal gland discharge, hyperpigmentation, or even flea infestations. More serious causes can include anal sac disease, cysts, or malignant tumors.

If you notice any black spots or crusts on your cat’s anus, it’s important to closely observe their behavior for any accompanying signs of discomfort or distress. Excessive grooming of the area, scooting, or visible discomfort may indicate an issue requiring attention.

There are several actions you can take to help alleviate minor concerns. Simple steps, such as cleaning the area with a damp cloth, trimming the fur around the anus, or administering flea treatments, can be effective in resolving common issues.

However, if you’re unsure about the cause of the black spots or crusts or suspect a more serious underlying issue, don’t hesitate to consult a veterinarian. They can perform a thorough examination, provide a proper diagnosis, and recommend an appropriate treatment plan. Seeking professional advice is especially important if you notice persistent black spots or crusts accompanied by other symptoms, such as changes in litter box habits or general behavior.
